我使用以下设置来列出代码。
\usepackage{listings}
\usepackage{textcomp}
\lstset{language=Java,
keywordstyle=\color{RoyalBlue},
basicstyle=\scriptsize\ttfamily,
commentstyle=\color{Green}\ttfamily,
rulecolor=\color{black},
upquote=true,
numbers=left,
numberstyle=\tiny\color{gray},
stepnumber=1,
numbersep=8pt,
showstringspaces=false,
breaklines=true,
frameround=ftff,
frame=single,
belowskip=3em,
belowcaptionskip=.25\baselineskip
}
实际的代码清单包含注释和 URL。如何确保只有注释会被着色,commentstyle
而不包含双斜杠的 URL//
也会被着色?
// This is a comment.
http://tex.stackexchange.com
在示例中将tex.stackexchange.com
是彩色的Green
。

您可以使用
morecomment=[l][basicstyle]{http://},
这使
\documentclass{article}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{textcomp}
\lstset{language=Java,
keywordstyle=\color{RoyalBlue},
basicstyle=\scriptsize\ttfamily,
commentstyle=\color{green}\ttfamily,
rulecolor=\color{black},
upquote=true,
numbers=left,
numberstyle=\tiny\color{gray},
stepnumber=1,
numbersep=8pt,
showstringspaces=false,
breaklines=true,
frameround=ftff,
frame=single,
belowskip=3em,
belowcaptionskip=.25\baselineskip,
morecomment=[l][basicstyle]{http://}, %<---- NEW BIT!
}
\begin{document}
\begin{lstlisting}
// This is a comment.
